本专题包括基因工程、细胞工程和胚胎工程三大部分内容,本专题主要和工农业生产和医学实践及科技发展联系在一起进行命题,考查考生的综合运用能力,“高起点、低落点”是本专题命题的最大特点。一、知识梳理1.基因工程的概念指在体外通过人工“剪切”和“拼接”等方法,对生物的基因进行改造和重新组合,然后导入受体细胞并使重组基因在受体细胞中表达,产生人类需要
This topic includes three major parts of genetic engineering, cell engineering and embryo engineering. This topic is mainly related to industrial and agricultural production and medical practice and development of science and technology to carry out propositions to examine the comprehensive utilization ability of candidates, “a high starting point, low point ”Is the most prominent feature of this topic proposition. First, the knowledge of combing 1. The concept of genetic engineering refers to in vitro by artificial “shear ” and “splicing ” and other methods to transform and recombine the biological genes, and then into the recipient cells and the recombinant gene in Recipient cells express human needs
